Functional Description The functional areas of the SL Rx 1900 are described in the following paragraphs. See Figure 4 for a functional block diagram of the SL Rx 1900. Dual Duplexed System

The SL Rx 1900 is a Filter-Amplifier that connects in-line (cascade) with the existing receiver equipment. Figure 2 shows a dual duplexed system with a cascade connection with a base station antenna. The block diagram shows the Bypass RF path, which provides pre-SL Rx 1900 performance if the Filter-Amplifier should develop a problem. The in-path dual duplexer allows the duplexed transmit power signal to route around the receive filter LNA (CoRE).

RF Signal Flow Dual Duplexed System RF signals from the Antenna are connected to the connector labeled ANTENNA. The output of the duplexer is connected internally to the Cryogenic RF Enclosure (CoRE). Inside the CoRE the signals connect to the first Bypass Relay. In normal operation the signals are connected to the band-specific superconducting filter and a Low Noise Amplifier (LNA) for each RF path. From the LNA, the signals go to the second Bypass Relay and then out of the CoRE to the dual duplexer and then the connector panel on the front of the SL Rx 1900 labeled BTS or PA. If a problem develops during normal operation, such as the CoRE dropping out of the operating temperature, or a loss of power, the system will automatically switch into Bypass mode. In Bypass mode, the RF signals from the Antenna are routed through the initial RF Bypass Relay, bypassing the SL Rx 1900 Filter-Amplifier and into the second RF Bypass Relay. In both SuperLink (Regulate state) and Bypass modes of operation, the RF signals from the second RF Bypass Relay are routed to the base station connector labeled BTS or PA. The SL Rx 1900 is set to Bypass mode on power up. In Bypass mode, both Bypass Relays switch together and connect the input to the output through a stripline circuit that bypasses the filter and LNA. The SL Rx 1900 system will automatically switch to SuperLink mode (Regulate state) when the CoRE has reached operating temperature. In SuperLink mode (Regulate state), the CoRE circuits provide highly selective filtering along with ~13 dB gain in each RF path. Simplexed System (Rx paths only) RF signals from the Antenna are connected to the non-duplexed RF input, Rx only (lightning protector). The output of the protector is connected internally to the Cryogenic RF Enclosure (CoRE) to the chassis. Inside the CoRE the signals connect to the first Bypass Relay. In normal operation the signals are connected to the band-specific superconducting filter and a Low Noise Amplifier (LNA) for each RF path. From the LNA, the signals go to the second Bypass Relay and then out of the CoRE to the connector panel on the front of the SL Rx 1900. If a problem develops during normal operation, such as the CoRE dropping out of the operating temperature, or a loss of power, the system will automatically switch into Bypass mode. In Bypass mode, the RF signals from the Antenna are routed through the initial RF Bypass Relay, bypassing the SL Rx 1900 Filter-Amplifier and into the second RF Bypass Relay. In both SuperLink (Regulate state) and Bypass modes of operation, the RF signals from the second RF Bypass Relay are routed to the base station receiver through a lightning protector. The SL Rx 1900 is set to Bypass mode on power up. In Bypass mode, both Bypass Relays switch together and connect the input to the output through a stripline circuit that bypasses the filter and


LNA. The SL Rx 1900 system will automatically switch to SuperLink mode (Regulate state) when the CoRE has reached operating temperature. In SuperLink mode (Regulate state), the CoRE circuits provide highly selective filtering along with ~13 dB gain in each RF path. Control The Digital Signal Processor (DSP) provides the SL Rx 1900 control and performance monitoring function. The DSP monitors: Input voltage from the Power Supply Driver power for the Cooling Motor Driver CoRE temperature from the Thermal Sensor Interface LNA current

If input voltage drops or rises to an unacceptable level the DSP will cause the SL Rx 1900 to switch into the Fault Bypass mode and, at the same time, activate the alarm relay. Signals from the alarm relay are available for connection to a base station alarm system. The FAULT LED, located on the SL Rx 1900 front panel, will illuminate RED to indicate Bypass mode. The DSP senses variations in driver power. If the motor driver power levels move to an unacceptable level the DSP will cause the SL Rx 1900 to switch into the Shutdown (Bypass) mode and, at the same time, activate the alarm relay as previously mentioned. The DSP controls the temperature of the CoRE. The Thermal Sensor Interface routes multiplexed sensor signals to the DSP. Correction signals are sent to the Cooling Motor Driver. If temperature levels move to an unacceptable level the DSP will cause the SL Rx 1900 to switch into the Fault Bypass mode. Additionally, the DSP monitors the LNA current. Unacceptable levels of LNA current will cause the SL Rx 1900 to switch to Fault Bypass mode. Each time the SL Rx 1900 is switched to Bypass mode, the alarm relay is activated. Cryogenic Cooling The STI Stirling Cycle Cryogenic Cooler is a highly efficient state-of-the-art Cryogenic Cooler. The Cryogenic Cooler maintains the CoRE at an operating temperature of ~79 K (Kelvin). The compressor and cold finger are fully integrated into a single self-contained unit. The Cooling Motor Driver provides drive and control to maintain a constant temperature. Temperature sensors in both the CoRE and the STI Stirling Cycle Cryogenic Cooler provide for constant temperature monitoring of the system by the Thermal Sensor Interface. Power Input power is received at the POWER terminal block connections located in the Junction Box on the side panel of the SL Rx 1900. Three power source options are available: AC (110 VAC or 220 VAC) or DC (27 VDC or -48 VDC).


AC The AC routes through the lightning protection, then to the AC/DC converter. DC The DC directly routes to the DSP controller board. The power is routed through a fuse. Dual Duplexers The Dual Duplexers work to route the RF transmit power around the CoRE, but at the same time allowing the receiver frequency signals to and from the CoRE with very low loss. This is accomplished using classical duplexer methods of tuned resonators, but using proprietary STI technology for superior performance in low loss, high power, and high rejection characteristics.

Integrating the SuperLink Rx 1900 with the Base Station

From this point forward, call service may be interrupted. It is recommended that this part of the installation be done during the maintenance window.

This portion of the procedure connects the SL Rx 1900 into the RF receive paths of the base station, using one sector as an example. The required cables are listed in Table 5, and the connections are shown in Figure 14.

1. Turn off the transmit power in the α sector.

2. Disconnect the RF jumper cable from the base station connector labeled Main α 0. Save the base station connector boot for reuse.

It is recommended that you turn off your cell phones while making power measurements. If your phone tries to register, it will alter the transmit power level.

3. Connect the power meter to the base station connector labeled α 0. Turn on the transmitter in Sector α for all provisioned carriers, Pilot, Page, Sync (PPS) only. Ensure a stable measurement before proceeding. Measure the reference power level and record the value. Turn off the transmit power.


4. Connect the RF jumper cable from the SL Rx 1900 connector labeled BTS or PA Sector α 1 to the base station α 0 connector. Reuse the base station connector boot.

5. Connect the power meter to the SL Rx 1900 connector labeled ANTENNA Sector α 1. Turn on the transmitter in Sector α for all carriers, PPS only. Measure, record, and verify that the measurement is within 1.5 dB of the recorded base station transmit value.

If the difference is greater than 1.5 dB, then troubleshoot the RF path beginning with the cables.

While the power meter is connected to the SL Rx 1900 ANTENNA connectors, the transmit power should be adjusted if desired.

Turn off the transmit power, and disconnect the power meter.

6. Add the connector boot to the antenna jumper cable and thread through the connector cover.

7. Attach the antenna jumper cable to the SL Rx 1900 connector labeled ANTENNA Sector α 1. This completes the connection for the first RF path.

If all remaining connections are duplexed, repeat the same integration steps for each connector one at a time. For Rx only paths, see the next section.

8. Using a Phillips #2 screwdriver (Table 4, Item 4), reattach the RF connector cover to the front of the cabinet. Using nylon wire ties (Table 5, Item 6), secure and weather proof the connector boots.

For Rx only paths

1. Disconnect the RF jumper cable from the base station connector labeled Diversity α 1. Save the base station connector boot (if applicable) for reuse.

2. Reconnect the same RF jumper cable to the SL Rx 1900 connector labeled ANTENNA α 2.

3. Take the loose end of the RF jumper cable attached to the SL Rx 1900 connector labeled BTS or PA α 2 and connect that to the base station connector labeled Diversity α 1. Reuse the base station connector boot.

4. Repeat these steps for all remaining Rx only paths.

5. After all sectors are complete, reinitialize the base station by power cycling.

6. Using a Phillips #2 screwdriver (Table 4, Item 4), reattach the RF connector cover to the front of the cabinet. Using nylon wire ties (Table 5, Item 6), secure and weather proof the connector boots.

Cause 5.1 SL Rx 1900 placed in Bypass mode.

Solution 5.1 From the System Status Portal, go to View > Set Points, and click the Relay tab to uncheck the Forced Bypass box and allow a chance for the system to reach SuperLink mode (Regulate state). If the FAULT LED turns off, the system is no longer in Bypass mode.

Cause 5.2 Other.


Fuse blows out or circuit breaker trips.

Cause 6.1 Incorrect voltage polarity applied.

Solution 6.1 Check that the voltage polarity matches the labels on the terminal block. If the polarity is correct, then continue with Cause 6.2. If the polarity is incorrect, change the polarity, replace the fuse, and/or reset the circuit breaker. Before you remove the fuse, turn off the circuit breaker to prevent injury.

To replace the fuse:

AC: Before you remove the fuse, turn off the circuit breaker to prevent injury. Remove the alarm surge protector, and unscrew the fuse cap on the left panel of the AC power surge protector using a Phillips #2 screwdriver. Remove the old fuse and replace with a new one. Reinstall the fuse cap and replace the alarm surge protector.

DC: Before you remove the fuse, turn off the circuit breaker to prevent injury. Remove the old fuse and replace with a new one.

Cause 6.2 Incorrect voltage applied.

Solution 6.2 Remove the fuse, close the circuit breaker, and check the voltage on the terminal block. Before you remove the fuse, turn off the circuit breaker to prevent injury. The voltage should read the following based on your system:

AC: 90 to 132 VAC, 180 to 264 VAC 27 VDC: 27+3 VDC -48 VDC: -48+4 VDC

Call the CS-Hotline if the voltage does not fall in this range.


Cause 6.3 Wrong circuit breaker rating.

Solution 6.3 If the circuit breaker trips, check the rating. The circuit breaker rating should read 5-amps for AC or 15 to 30 amps for DC. Replace the circuit breaker if necessary.

Cause 6.4 Other.


The SL Rx 1900 does not reach SuperLink mode (Regulate state) after five hours.

Cause 7.1

SL Rx 1900 is in Bypass mode.

Solutin 7.1 Check if the FAULT LED is flashing RED. If so, the system is in Bypass mode. Set the system to SuperLink mode (Regulate state). From the System Status Portal, go to View > Set Points and click the Relay tab to uncheck Forced Bypass box. Allow time for the system to reach SuperLink mode (Regulate state). When the FAULT LED turns off, the system is in SuperLink mode (Regulate state). If the problem persists, call the CS-Hotline.

Cause 7.2 Source voltage is low under load.

Solution 7.2 Measure the voltage with a DMM. Replace the power wire and/or breaker if necessary.

Cause 7.3 Other.

Solution 7.3 Establish communication with the system using the System Status Portal (Start > Programs > STI > STI System Status Portal). With the program open, click Communicate with Unit to connect to a Comm Port, and establish communication with the SL Rx 1900. To observe the Cold Stage Wide Range Temperature, from the System Status Portal, choose View > Status > Measure. Review the temperature. If the temperature is not in the range of 79+4 K, call the CS-Hotline.


Problem 8

Alarm Relay Test failed.

Cause 8.1 Relay wire is not making a proper connection.

Solution 8.1 Use an ohmmeter to measure connectivity from the SL Rx 1900 to the alarm relay. If either connection is bad, reset the wires or replace them and try connecting again. If both connections are good, see Cause 8.2.

Cause 8.2 Alarm has been mis-wired.

Solution 8.2 Ensure that the one wire is connected to the terminal block connection labeled C and one wire is connected to NC or NO.

Cause 8.3 Alarm cable fault (alarm on, but front panel does not show a RED LED).

Solution 8.3 Inspect alarm cable and connections at both ends. Set and reset the alarm by checking the Forced Bypass box in the System Status Portal (go to View > Set Points and click the Relay tab to check or uncheck the Forced Bypass box), and check the operation at both ends of the alarm cable. See the “Connecting the Alarm Relay” section on page 33 for more information.

Cause 8.4 Other.


Receive Path Gain Test failed.

Cause 9.1 Attempting to measure backwards or cross receive paths.

Solution 9.1 Recheck the connection to the SL Rx 1900, and try the receive path gain test again.

Cause 9.2 Used wrong test frequency.

Solution 9.2 See Table 11 to verify the frequency band, and try the receive path gain test again.

Cause 9.3 Test setup error. The SL Rx 1900 is not in SuperLink mode (Regulate

state).

Solution 9.3 Ensure that you inject the signal into the DIN 7/16 ANTENNA ports and that they are measured at the BTS or PA ports with the same receive path number.

Cause 9.4 Other.



Problem 10

In SuperLink mode (Regulate state), the alarm signals when the RF cable is connected between the SL Rx 1900 BTS port and the BTS antenna input.

Cause 10.1 DC bias is on the center conductor of the coaxial cable.

Solution 10.1 Some base stations allow for DC bias on the coaxial line to provide power to a tower mount amplifier. Measure the DC bias from the center conductor to the ground of the BTS antenna connector. If there is bias, consult the BTS documentation to turn off the Tower Top Amplifier bias voltage.

Cause 10.2 Tower Top Amplifier still connected.

Solution 10.2 Climb the tower and remove the Tower Top Amplifier. This causes problems for both the SL Rx 1900 input and/or output if the DC power is connected.

Cause 10.3 Other.

Solution 10.3 Call the CS-Hotline. Operation Troubleshooting

Problem 11

FAULT LED is RED (Alarm is on).

Cause 11.1 SL Rx 1900 has input power out-of-range condition.

Solution 11.1 Establish communication with the system using the System Status Portal (Start > Programs > STI > STI System Status Portal). With the program open, click Communicate with Unit to connect to a Comm Port, and establish communication with the SL Rx 1900. Verify the alarm and characterize the problem. Take note of any logged faults.

If the problem is input power, use a DMM to investigate the problem. Based on your system, the input power should be the following:

o AC: 90 to 132 VAC, 180 to 264 VAC o 27 VDC: 25 to 30 VDC o -48 VDC: -32 to -58 VDC

If the problem persists, call the CS-Hotline. Cause 11.2 Other.



Problem 12

RF Performance is not optimal, detected by the following conditions: Degradation in statistical performance Customer complaints Base Station Built-in Test (BIT) failure

Cause 12.1 Open/short in SL Rx 1900 receive path.

Solution 12.1 Check the gain of each receive path of the SL Rx 1900, one receive path at a time. Turn off the BTS transmitters. Inject the RF signal to the antenna port of the SL Rx 1900, and sample the signal at any point further up the RF receive ports. Check the measurement in SuperLink mode (Regulate state) and record. Place the system into Forced Bypass mode (with the System Status Portal open, go to View > Set Points and click the Relay tab to check the Forced Bypass box), and then recheck the measurement. The difference between the two readings should be ~13 dB. Check each subsequent receive path in the same manner. If you discover a receive path that is not ~13 dB in SuperLink mode (Regulate state), but in Forced Bypass mode, call the CS-Hotline.

Cause 12.2 Other.


Abnormal SL Rx 1900 noise.

Cause 13.1 SL Rx 1900 becomes abnormally loud.

Solution 13.1 Check for loose mounting hardware, cover screws, and other hardware.

Check the FAULT LED. If the FAULT LED illuminates RED, the system may be recovering from power drop out. Wait three hours to allow it to recool. When LED turns off, listen to the system again for normal vibration, and sound level.

Cause 13.2 Other.



Problem 14

No power is available to the system, but voltage is detected.

Cause 14.1 The power surge protector was hit by lightning, or no power is observed at

the system.

Solution 14.1 AC: Check the AC input power. If the power is 90 to 132 VAC, 180 to 264 VAC, then check the AC surge protector output power. If the voltage is out of range, then turn off the circuit breaker and check the fuse. Replace the fuse if necessary. Before you remove the fuse, turn off the circuit breaker to prevent injury.

DC: Turn off the circuit breaker and check the fuse. Replace the fuse if necessary. Before you remove the fuse, turn off the circuit breaker to prevent injury.

Cause 14.2 The alarm surge protector was hit by lightning, or no power is observed at

the system.

Solution 14.2 AC and DC: See page 37 to test the Alarm connections. Test the “unprotected” alarms. If the alarms fail, test the “protected” alarms. If the alarms pass, then the lightning protection needs replacing. Contact the CS-Hotline.

Cause 14.3 Other.



Chapter 7 Periodic Visual Inspection

The SL Rx 1900 is maintenance free. However, the following periodic visual inspection steps are suggested. The frequency of inspections depends on the installation site conditions. Check that ventilation spaces on the top rear and bottom of the SL Rx 1900 are clear of

debris. Check the cabinet for damage. Check that the mounting hardware is tight and the SL Rx 1900 is securely mounted. Check the seals around the RF connector covers and connector boots on the cables. Check the connector boots for wear. Look for damaged RF cables. Check the FAULT LED. When the system is in Bypass mode, the FAULT LED
